Connective

tissue type

Structure Function Location Diagram/Photo

Areolar (loose

connective)

jelly matrix; has

network of

elastic fibres

which attach

together

holds the organs

in place,

cushions and

protects organs

(acts as a

packing

material)

surrounds blood

vessels and

nerves ad found

in the mesentry

which

surrounds the

intestine

connective tissue.

White fibrous consists of

non-elastic

fibres

acts as a shock

absorber,

transfers or

absorbs forces

in tendons,

ligaments and

many tough

membrane

sheaths that

surround organs

fibrous tissue.

Cartilage rubbery matrix,

can be flexible

or rigid

gives structure,

shape and

strength;

reduces friction;

provides

support

joints, nose,

sternum,

trachea

Cartilage.

Bone tissue made up of

collagen fibres;

mineralised

with calcium

and phosphates

to make it solid

provides

strength and

support; creates

red blood cells

and white blood

cells;

bones found all

over the body

Osteoclast, a type

of bone tissue.

Blood DUMMY

Blood is regarded as a specialised form ofconnectivetissue because it originates in the
bones and has some fibres. Blood is composed of red blood cells, white blood cells and
platelets. These components are suspended in a yellow fluid known as plasma.
